Abstract: This application provides a communication method and a communication apparatus. In a technical solution of this application, when a preset condition is met, an access network device notifies user equipment that a multicast session is to be released or is to be deactivated. If the multicast session is being used or is to be used, the user equipment may feed back to the access network device that the user equipment is still interested in a multicast service. The access network device may determine, based on whether the feedback from the user equipment is received within a preset time period, whether to continue to release or deactivate the multicast session. In this way, when user equipment in an idle state can receive multicast data, this technical solution can properly manage the multicast session.

Abstract: This application discloses an information exchange method and apparatus. In the method, a terminal device transmits attach request information to a core network device, receives attach accept information of the core network device, where the attach accept information includes a first integrity check code; the terminal device obtains a second integrity check code based on the attach accept information; and the terminal device obtains, if the first integrity check code is the same as the second integrity check code, a third integrity check code based on encrypted attach complete information, and transmits encrypted attach complete information to which the third integrity check code is added to the core network device. This reduces data exchange procedures, reduces an amount of data of exchanged information, and reduces a time consumed in an information exchange process performed between the terminal device and the core network device.

Abstract: Embodiments of the present disclosure disclose a method, an apparatus, and a system for data transmission. The method includes: broadcasting, by a relay device, a first message, where the first message is used to indicate that the relay device supports data forwarding; receiving, by the relay device, a second message from a remote device, where the second message includes data of the remote device; and sending, by the relay device, the data to a core network device based on the second message. In the present method, after receiving the first message broadcast by the relay device, the remote device directly sends the data of the remote device to the relay device without establishing a connection dedicated for transmitting the data of the remote device between the remote device and the relay device, thereby reducing signaling and reducing power consumption of the remote device.

Abstract: A secure communication method and a core network node are provided. In the method, a first core network node in a home public land mobile network (HPLMN) receives a first data authentication request sent by a core network node in a visited public land mobile network (VPLMN), and sends a second data authentication request to a home location register (HLR) or a home subscriber server (HSS). The HLR or the HSS generates an end-to-end security key. The first core network node in the HPLMN sends the end-to-end security key to a second core network node in the HPLMN. The second core network node in the HPLMN performs, based on the end-to-end security key, secure communication with a terminal that has roamed to the VPLMN.
